Hell freezes over and pigs fly before the Steelers beat the Ravens at M&T with a backup QB. M&T is the best home field advantage in football. 16 straight wins and longest win rate in NFL. Lefty will sh*t his pants walking into that stadium.
It's possbile, but highly unlikely. Even with Ben coming back it's a long shot (assuming he's not 100 percent in two weeks). Picturing Lefty pooping his pants made me laugh though...he just has that face.
